You have a lot of questions here, I can help with some.
1) To find the inverse, switch the x and f(x) and solve for f(x).
x = 3f(x) - 7
x + 7 = 3(f(x)
(x + 7) / 3 = f(x)
2) It is a function, because each input pairs with only 1 output.
3) Any diagonal line would be a function.
4 - 8 (We can't do without the diagram)
9) f(-9) = 3(-9) - 6
f(-9) = -27 - 6
f(-9) = -33
10) f(-2) = 42 + 3
f(-2) = 45

Step-by-step explanation:
So what is the average rate of change? Basically, it's the slope. In fact it's exactly the slope for a linear equation, but how do you find slope?
Sp we just plug the values in.
8 * m - 2 = 8 * 4 - 2 = 30
